Uros are awesome. I have never ha a bearded dragon but uros do need a lot higher temp. They only really eat veggies too. They get their protein from dried beans. I keep wood on top of my tank to help keep the temp up and contain the heat.

I got 3 right now and will be picking another up this weekend.

They need a pretty big tank too. 4x2 works but I find having a longer tank then that makes it easier to still have a cool end with such high temps.

You can keep more then one though in a tank which is cool but you can't have multiple males and it is really hard to sex uros. Their are guidelines to sexing them but even Rhodes don't always work out.
